Cable Tray Installations
Cable tray is a sheet steel channel with multiple holes. It is used extensively on large industrial and commercial installations for supporting NYM cables, Steel Wire Armoured cables ( SWA
), Fire Performance cables such as FP200, Mineral Insulated ( MI ) etc. They are laid on the tray and secured at appropriate intervals with cable ties passed through the tray holes.
Fire Performance cables should be clipped to tray or wall etc. using copper or stainless steel clips and brass screws or bolts as suitable.
A wide range of cable tray types and accessories is available to match any cabling requirement. Cabling requirements can range from the lightest instrumentation cables through to the heaviest multi-core power cables.
Cable Tray Finishes
Hot dip galvanised finish is the most frequently used. This finish is suitable for use in environments with high or low ambient temperatures and where normal atmospheric pollutants are likely to be encountered. The galvanising is applied to conform to BS 729 standard.
Other tray finishes less frequently encountered are available e.g. PVC. Cable tray finishes may be selected to suit a particular installation environment e.g. stainless steel tray is available for use in food processing plants.
